Description

Technical Field

[0001] The utility model relates to the technical field of sounding equipment, and particularly to a dynamic sounding equipment. Background Art

[0002] Civil engineers try to use various simple tools and methods to detect the properties of soil layers to assist the design and construction of foundation engineering. Its working principle is to use a heavy hammer of a certain mass to freely fall from a specific height, transfer the energy through the sounding rod to the probe head, and make the probe head penetrate into the soil. According to the number of hammer blows required for the probe head to penetrate a certain depth, the properties of the soil layer, such as density and bearing capacity, are judged.

[0003] For traditional dynamic sounding equipment, such as a manual drop hammer type dynamic sounding instrument, it is necessary to manually lift the heavy hammer and let it freely fall. This process not only has a large labor intensity but also low efficiency. During manual operation, it is difficult to accurately control the height, strength, and frequency of the hammer blow, which easily leads to errors in the test results. Summary of the Utility Model

[0040] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0041] Referring to Figures 1 to 4 , a first embodiment of the present invention provides a dynamic penetration testing device, which includes a frame 1; a sliding frame 2 is vertically slidably arranged on the frame 1; a percussion hammer 3 is vertically slidably arranged in the sliding frame 2; one end of a sounding rod 4 has a first step 401, the sounding rod 4 is slidably arranged at one end of the sliding frame 2 close to the ground, the other end of the sounding rod 4 extends out of the sliding frame 2, and after the percussion hammer 3 slides, it abuts against the first step 401 to push the sounding rod 4 into the ground; a first telescopic member 5 is arranged in the sliding frame 2, and one end of the percussion hammer 3 is arranged at the extending end of the first telescopic member 5.

[0042] In this embodiment, to solve the problem of manual dynamic sounding required in the related art when detecting the properties of soil layers, a dynamic sounding device is designed. Among them, the frame 1 plays an overall supporting role, which can be made of strong metal materials to ensure stability in various working environments. The sliding frame 2 is vertically slidably arranged on the frame 1 through a specific guide rail structure, enabling the sliding frame 2 to smoothly move up and down on the frame 1. The impact hammer 3 is also made of high-strength metal material to ensure that it will not be easily damaged during repeated impacts. The vertical sliding of the impact hammer 3 within the sliding frame 2 is achieved through a precisely designed guide chute, ensuring the accuracy and stability of its movement. One end of the sounding rod 4 has a first step 401, and the sounding rod 4 is slidably arranged through a specific hole at one end of the sliding frame 2 close to the ground. When the impact hammer 3 slides downward under the action of the first telescopic member 5, the impact hammer 3 abuts against the first step 401 of the sounding rod 4, thereby pushing the sounding rod 4 closer to the ground to achieve sounding of the ground. The first telescopic member 5 is arranged within the sliding frame 2, such that the extending end of the first telescopic member 5 can precisely push the impact hammer 3 to perform vertical sliding.

[0043] The advantage is that through the reasonable design of structures such as the frame 1 and the sliding frame 2, the entire device has high stability during operation, can withstand the repeated impacts of the impact hammer 3 and the acting force of the sounding rod 4 on the ground, and ensures the long-term stable operation of the device. The setting of the first telescopic member 5 can precisely control the movement of the impact hammer 3, thereby achieving precise pushing of the sounding rod 4. This makes the sounding process more accurate and enables the acquisition of more accurate sounding data.

[0044] Furthermore, the first telescopic member 5 includes an oil pump, an oil tank, a pressure regulating valve, and a control valve.

[0045] In this embodiment, the first telescopic member 5 includes an oil pump, an oil tank, a pressure regulating valve, and a control valve. The oil pump can be selected as a hydraulic oil pump with high efficiency and stable output. The oil tank is designed with sufficient capacity to ensure that sufficient hydraulic oil can be provided for the continuous operation of the device. The pressure regulating valve can precisely adjust the pressure of the hydraulic system according to different sounding requirements.

[0046] During actual operation, when it is necessary for the impact hammer 3 to descend for percussion, the control valve adjusts the flow direction of the hydraulic oil, causing the impact hammer 3 to quickly descend under the action of the oil pressure, strike the step of the sounding rod 4, and push the sounding rod 4 deep into the ground.

[0047] The advantage is that through the cooperation of the oil pump, the pressure regulating valve, and the control valve, precise control of the movement of the impact hammer 3 can be achieved. The magnitude and frequency of the impact force can be adjusted according to different geological conditions and sounding requirements, improving the accuracy of the sounding results.

[0048] Furthermore, one end of the impact hammer 3 is hinged to the extending end of the first telescopic member 5.

[0049] In this embodiment, one end of the impact hammer 3 is hinged to the extended end of the first telescopic member 5. For example, a connecting ear can be provided at one end of the impact hammer 3, and a corresponding connecting shaft can be provided at the extended end of the first telescopic member 5, and the hinged connection is achieved through the cooperation of the connecting ear and the connecting shaft. Such a design enables the impact hammer 3 to adjust its angle and position more flexibly during movement.

[0050] When the first telescopic member 5 pushes the impact hammer 3 to move downward, due to the hinged setting, the impact hammer 3 can make a certain degree of adaptive adjustment according to the position and angle of the sounding rod 4, ensuring that it can accurately abut against the step of the sounding rod 4, thereby effectively transmitting the impact force. After the impact is completed, the first telescopic member 5 contracts to drive the impact hammer 3 to rise, and the hinged structure can also make the impact hammer 3 more stable during the rising process, reducing shaking and unstable factors.

[0051] The advantage is that the hinged setting enables the impact hammer 3 to better cooperate with the sounding rod 4, ensuring that each impact can be accurately transmitted to the sounding rod 4, improving the accuracy of the sounding result. It can adapt to sounding rods 4 at different angles and positions, improving the adaptability of the equipment under complex terrain and working conditions.

[0052] Further, one side of the frame 1 has ratchet teeth 6, and a ratchet pawl 7 is also included. One end of the ratchet pawl 7 is rotatably arranged on the sliding frame 2, and the other end meshes with the ratchet teeth 6; both ends of the elastic member 8 abut against the ratchet pawl 7 and the sliding frame 2 respectively, for providing a force for the other end of the ratchet pawl 7 to approach the ratchet teeth 6.

[0053] In this embodiment, a series of regularly arranged ratchet teeth 6 are provided on one side of the frame 1. One end of the ratchet pawl 7 is rotatably connected to the sliding frame 2. The ratchet pawl 7 is integrally curved, and its shape fits the contour of the ratchet teeth 6, and it can closely mesh with the ratchet teeth 6.

[0054] One end of the elastic member 8 is fixed on the ratchet pawl 7. The other end of the spring abuts against the sliding frame 2, to ensure that the elastic member 8 can exert a stable acting force on the ratchet pawl 7, so that the ratchet pawl 7 is always in contact with the ratchet teeth 6.

[0055] When the first telescopic member 5 extends and pushes the impact hammer 3 to slide downward to prepare to strike the sounding rod 4, at the moment when the impact hammer 3 is about to strike the sounding rod 4, if there is an external vibration or other interference that may cause the sliding frame 2 to shake upward, the ratchet pawl 7 will firmly engage with the ratchet teeth 6, ensuring that the sliding frame 2 will not move upward, so as to ensure that the impact hammer 3 can accurately strike the sounding rod 4 for effective sounding operation.

[0056] The advantage is that the cooperation between the ratchet 6 and the pawl 7 can prevent the sliding frame 2 from sliding upward at the critical moment when the impact hammer 3 slides down to hit the feeler rod 4, thereby ensuring that the impact hammer 3 can stably transmit the impact force to the feeler rod 4, ensuring the accuracy of the feeler operation and improving the reliability of the feeler result. During the feeler process, the equipment will be affected by various forces, and the design of the pawl 7 and the ratchet 6 can effectively resist these forces, keep the position of the sliding frame 2 stable, and thus enhance the stability of the entire equipment and reduce the error and safety risks caused by the shaking of the sliding frame 2.

[0057] Furthermore, it also includes a sliding rod 9, which is slidably set on the sliding frame 2, and the elastic member 8 is set on the sliding frame 2 at one end away from the pawl 7 through the sliding rod 9. After the sliding rod 9 slides, the pawl 7 and the ratchet 6 are released from abutment.

[0058] In this embodiment, the sliding rod 9 is a cylindrical metal rod to ensure smooth sliding on the sliding frame 2. The sliding frame 2 is provided with a slideway matching the sliding rod 9, and the sliding rod 9 can slide freely in the slideway. The end of the elastic member 8 away from the pawl 7 is connected to the sliding rod 9 through a connecting ring. The connecting ring can be moved on the sliding rod 9 to adjust the direction and magnitude of the force of the elastic member 8 on the pawl 7. When it is necessary to release the abutment between the pawl 7 and the ratchet 6, the operator can push the sliding rod 9 to slide in the slideway, and use a fastener to limit the relative position of the sliding rod 9 after sliding into place.

[0059] For example, in order to enable the sliding frame 2 to move upward, the operator pushes the sliding rod 9 to slide in a specific direction and then tightens the sliding rod. The movement of the sliding rod 9 reduces the force of the elastic member 8 on the pawl 7, and the pawl 7 gradually separates from the ratchet 6, thereby releasing the locking of the sliding frame 2. When the sliding frame 2 needs to be locked again, the operator pulls the sliding rod 9 back to the initial position to lock it again, and at the same time pushes the pawl 7 to re-engage with the ratchet 6.

[0060] The advantage is that, by operating the sliding rod 9, the meshing state of the pawl 7 and the ratchet 6 can be conveniently controlled to achieve locking and unlocking of the sliding frame 2. In different working stages, the movement limit of the sliding frame 2 can be flexibly adjusted as needed, thereby improving the flexibility and adaptability of the device operation.

[0061] Furthermore, it also includes a fixed pulley 10, which is in a certain number and is respectively arranged on the top of the frame 1 and the upper surface of the sliding frame 2; a transmission rope is used to link the certain fixed pulleys 10; a reel 12 is rotatably arranged on the frame 1 and is used to reel in the transmission rope, and after the reel 12 is reeled in, the sliding frame 2 is away from the ground.

[0062] Further, one end of the reel 12 has a first set of teeth 1201. It further includes a second telescopic member 13. The second telescopic member 13 is arranged on the frame 1, and the reel 12 is rotatably arranged at the extended end of the second telescopic member 13. A first driving member 14 is arranged on the frame 1. The output end of the first driving member 14 has a second set of teeth 1401. After the second telescopic member 13 extends and retracts, the first set of teeth 1201 and the second set of teeth 1401 abut or disengage from each other.

[0063] In this embodiment, several fixed pulleys 10 are respectively installed at specific positions on the top of the frame 1 and the upper surface of the sliding frame 2. Through reasonable layout, it is ensured that the transmission rope can smoothly transmit between the fixed pulleys 10. The transmission rope is selected as a strong and durable steel wire rope, which has sufficient strength and flexibility and can bear the weights of components such as the sliding frame 2 and the impact hammer 3. The transmission rope bypasses each fixed pulley 10 in turn to form a closed transmission loop. The reel 12 is installed on the extended end of the second telescopic member 13 and can rotate freely.

[0064] The surface of the reel 12 is specially treated to increase the friction with the transmission rope, ensuring the stable and reliable winding and unwinding of the transmission rope on the reel 12. The second telescopic member 13 can be a hydraulic telescopic cylinder or an electric telescopic mechanism. When it is necessary to connect or disconnect the reel 12 from the first driving member 14, the second telescopic member 13 extends or retracts, driving the reel 12 to move in the horizontal direction. The first driving member 14 can be a motor or other power devices. The second set of teeth 1401 at the output end of the motor matches the first set of teeth 1201 at one end of the reel 12. When the second telescopic member 13 extends and the first set of teeth 1201 and the second set of teeth 1401 abut, starting the motor can drive the reel 12 to rotate, thereby winding the transmission rope and lifting the sliding frame 2 away from the ground, realizing the lifting and reset operation of the sliding frame 2.

[0065] Further, it further includes casters 15. The number of casters 15 is several, and several casters 15 are all rotatably arranged on the lower surface of the frame 1.

[0066] In this embodiment, the number of casters 15 can be reasonably selected according to the size and weight of the equipment, generally four. Each caster 15 is rotatably arranged on the lower surface of the frame 1 through a sturdy mounting bracket. The mounting bracket is fixed to the frame 1 by means of bolt connection or welding to ensure that the casters 15 will not loosen or fall off during the movement of the equipment. The casters 15 can be universal casters 15, enabling the flexible movement of the equipment in all directions.

[0067] The advantage is that the setting of the casters 15 enables the dynamic penetration equipment to be easily transferred between different working locations, improving the mobility and flexibility of the equipment. The operator does not need to use large lifting equipment or consume a large amount of manpower and material resources for handling, greatly saving time and cost.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
